The protein content constituent and its production manner null of the neutral area where cohesion of the protein

摘要

PROBLEM TO BE SOLVED: To provide a neutral protein-containing composition free from producing aggregate even if mixing a raw material containing Ca and/or Mg and providing heat sterilization at ≥100°C, and excellent in palate feeling and flavor, and to provide a method for producing the protein-containing composition.;SOLUTION: This composition having pH in a neutral area contains either Ca or Mg, or both of them, and protein and is heat sterilized. Furthermore, the composition contains pectin with a low methyl esterification degree to prevent aggregate of protein, and contains no other additive for aggregate prevention. The method for producing the neutral protein-containing composition which prevents protein from aggregating, includes mixing a raw material which contains Ca or Mg, or both of them and a protein-containing raw material with pectin with a low methyl esterification degree, heat-sterilizing the mixture thus obtained at ≥100°C, aseptically filling or hot packing the mixture thus obtained after heat sterilizing. Alternatively, the method for producing the neutral protein-containing composition which prevents protein from aggregating, includes mixing a raw material which contains Ca or Mg, or both of them and a protein-containing raw material with pectin with a low methyl esterification degree, and filling and sealing the mixture thus obtained in a container followed by heat-sterilizing.;COPYRIGHT: (C)2008,JPO&INPIT
